    Calibration Rods

    Also known as calibration standards, these rods let you check and set micrometers and other measuring tools. For accuracy, they’re precision ground to extremely tight length tolerances. They have insulated plastic handles to minimize heat expansion.

    Included

    Maintain the accuracy of variance indicators. Because indicators lose accuracy with normal use, regular checks with these testers keep your readings precise. Insert plunger or lever variance indicators into the clamp and turn the graduated disc. You’ll know your indicator is calibrated if its readout matches the tester’s graduations.
